Luther Kountze (October 29, 1841 – April 17, 1918) was an American banker, responsible for helping the city of Denver, Colorado in a time of need and leaving a philanthropic legacy in Morristown, New Jersey.

He founded a late-19th century national banking dynasty along with his brothers Charles, Herman and Augustus.

Late that year and into the next, Kountze worked with several other investors to form the company that would eventually become the Denver Pacific Railroad and Telegraph Co.[3] Luther left Colorado for New York in 1867.

In 1881, Luther moved to Morristown, New Jersey and built an English-style estate designed by George E. Harney.

He contributed a large part of the land that now forms the National Jockey Hollow Park in Morristown, NJ.
